The tongue, 11, is initially in the plane of the body of the seal and is folded along the line, 10, and in this form passes through the alined apertures in the locking mechanism. i

After he folded end of the inserted seal has been unfolded or opened out to the form shown in Fig. 1, the tongue, 11, is bent along the line, 12, to perpendicular posi- I have ascertained that it is practicable to produce sheet material, particularly sheet metal, of such limited pliability as to Withstand or permit a definite or predetermined limited number only of fleXions or bends, and in making my improved seal l so limit its pliability along the fold line, 10, as to permit of its being folded and unfolded once only, and l similarly limit its pliability along its lines of bend of the caues the sheet metal having in the applying of the seal to the locking mechanism been bent once along the lines of bend of the tongues, 9 and 11, and having been folded and unfolded along the fold line, 10,

a repetition of these bending and folding operations Will break the metal along said line of fold and said lines of bend, thereby destroying the seal.

lt is therefore comparatively easy for an inspector to at a glance determine Whether the seal has been broken; and so long as the sealremains intact it is apparent that the locking mechanism of the car doorhas not been opened. A,

The seal is customarily provided With embossed or stamped characters indicating the transportation line, as the initials l?. R. R., and other characters identifying the particular car, as the number 9827.

I prefer to place one at least of the numerals forming the number identifying the particular car, on the foldable portion of the seal, so that if said portion is broken olf the completeness of the identifying number is destroyed.

1 have shown the body of the seal formed With a tongue, 13, parallel With the shank, 7, but said tongue may be omitted if desired. 1f desired the keepers or buttons, 5, may be omitted and the seal alone relied upon for preventing removal of the hasp from the staple, 3.

As the seal is preferably made of quite thin sheet metal, l prefer to rely upon the keepers or buttons, 5, for securing the hasp upon the'staple.

The sheet metal may be weakened along the lines of bend of the tongues, 9 and 11, and along the line of fold, 10, by scoring the metal or by means of slots, 14, or in any other known manner whereby the plie-.bility of the metal at these lines of bend and fold can'be limited to the degree above. set forth.

While the head, 8, and tongue, 13, may be made of such dimensions as to of them'- selves prevent Withdrawal to the right the seal from the openings in the locking mechanism, l prefer the additional security provided by the tongue, 9, to prevent any possibility of such removal by distortion of the tongue, 13, or head 8f The tongue, f3, is preferably formed With an offset, 13a, Which is interposed between the apertured members, 3 and 5a, of the locking mechanism, and the unfolded locking Wing or member 7b, as shown in F 1, thereby preventing impact of said locking member, 7b, With said apertured members of the locking mechanism.

ln Fig. 6, l have shown a modified form of seal embodying my invention, the seal comprising 'a body longitudinally slitted at 14, to form twoV legs or branches, v15 and 16, the branch, 15, having atits end a Wing, 17, foldable along the line, 1S, and the member, 16, having brazed or Welded thereto a crosspiece, 19, formed With a. vertical slot, 20, adapted to permit the passage therethrough of the end of leg, 15, with the Wing, 17, folded over thereupon as yshovvn in Fig. 7.

In applying the seal, one of the branches or legs, 15, 16, is passed through the staple, 3, of the locking mechanism after which the leg, 15, With the Wings, 17, folded over thereupon is passed through the slot, 20, and the Wing, 17, is unfolded toits original position in the plane of the body of the seal.

The leg, 15, cannot thereafter be Wthl drawn from the opening, 20, in the locking mechanism thus provided Without refolding the Wing, 17, upon the leg, 15; and by making the sheet material along the fold line, 18, of suoli limited pliability as to permit the same to` be folded only once, such refolding cannot be accomplished Without destroying the seal. v

1n Fig. 8 l have shown another form of seal embodying the invention comprising a sheet metal body longitudinally slitted 21, to form tvvo branches or legs, 22, 23, one, 23, of which has at` its end an L-shaped off. set, 24, provided vvithr a vertical slot, 25, and the other, 22, of Which is formed With an extension, 22a, secured to the leg, 22, by means of an integral loop or tongue, 26, insertedI through an aperture, 27, in the leg, 22, and Welded or brazed to said leg.

The extension, 22"?, has a Wing, 28, foldable over thereupon along the longitudinal line, 29, and said extension and Wing are of such dimensions that when the Wing is so folded they can be passed through the slot, 25, in the offset, 24, of the member, 28.

In applying the seal, one of the legs, 22, 28, is passed through the staple of the locking mechanism, the extension, 22a, with the Wing, 28, folded over thereupon is then passed through the slot, 25, in the offset, 24, after Which the Wing, 28, is unfolded or opened out to its original position in the plane of the body of the seal in substantially the same manner as the seal shown in Figs. 6 and 7 and is applied.

The metal along the fold line, 29, is of the limited degree of pliability above described With respect to the seal shown in the other figures.

Ido not Wish to be limited to the constructions shoWn and above described, as, for oer* tain purposes of the invention, various changes may be made in the form and arrangement of various parts of the device without departing from the spirit of the invention.

I claim: Y

l. A device of the class described having a member of sheet material foldable to a form and size insert-ible through an aperture in a locking mechanism and incapable When unfolded of Withdrawal from said aperture, said sheet material being of such limited plia-bility at the fold line as to permit of being folded and unfolded once only, said fold line being visible on the face of the device When unfolded to locking position.

2. A device of the class described having a shank insertible through an aperture in a locking mechanism, and at one end of said shank means for preventing Withdrawal thereof in one direction, and at the other end of said shank a member of sheet materia-l foldable to a form and size insertible through an aperture in a locking mechanism and incapable When unfolded of Withdrawal from said aperture, said sheet material being of such, limited pliability at the fold line as to permit of being folded and unfolded once only, said fold line being Visible on the face of the device when unfolded to locking position.

8. A device of the class described having a shank insertible through an aperture in locking mechanism, and at one end of said shank means for preventing Withdrawal thereof in one direction, and at the other end of said shank a member of sheet material foldable to a form and size insertible through an aperture in a locking mechanism, and when unfolded serving to lock said shank against Withdrawal in the opposte direction, and having a tongue bendable along a line at right angles to the fold line of said member to a position to lock said shank against Withdrawal in said opposite direct-ion, said sheet material being of such limited pliability at said fold line and said line of bend as to permit of said member and said tongue being folded or bent to locking position once only.
